I've seem some Super A's with a rear rockershaft. I have none on my Super A, but it looks like I'll need one to put on a 3-pt hitch conversion?

While my Cub has one little arm sticking out, the Super A's I've seen have two large arms, curved downard at the ends and with two holes through them flatwise on the curved tips. It looks like the 3-pt conversion kits hook into these arms at the top.

Was this only supplied as part of the Fast-Hitch, or is this what is known as a 2-pt. hitch? Or...?

Allen, this isn't a very good picture of my Super A 3 point, but it shows the arms you are talking about. Someone correct me if I'm wrong, but I think the rockshaft was standard equipment on the Super A. At least I've never seen one without it unless it was taken off. There are a couple on e-bay now I think. I've seen them go for over a hundred dollars down to 50 dollars. I just gave one away. The Super A had a square tool bar on the rear that you had to bolt the plows to, but it still required the rockshaft. But even back in the 50s you could get your dealer to install an after market 3 point if you paid him enough. This 3 point can be made for a hundred dollars or less. The rockshaft will be the most expensive piece. If you would like more pictures, I can e-mail you all you want.

That is the rear rockshaft from before Fast-Hitch came along. It was not a standard part of the tractor but was a separate attachment required for many implements -- just like the one arm roackshaft on the Cub.
